w= 8
Answer:
10 Girls
Step-by-step explanation:
Total number of girls in Alden Middle school= 25 girls
Percent of girls play for travel team= 40%
We have to find the numbers of girls who play for middle school team
Numbers of girls who play for middle school team= 25 ×
Numbers of girls who play for middle school team=25 ×
Numbers of girls who play for middle school team=10
Hence the number of girls play for travel team= 10 girls.
Hence, the correct answer is 10.

Answer:
x = 1.566
Step-by-step explanation:
7^2=12^x
- 7^2 means 7 squared, which is 7*7, which is 49.
49 = 12^x
- Now we have to use logarithms to figure this out! Logarithms are like the opposite of exponents.
Exponential: b^x = y
Logarithmic: logb(y) = x.
- Now with 49 = y, 12 = b, we plug in to get x:
logb(y) = x
log12(49) = x
Plug this in your calculator (on a TI-84, it's MATH -> A)
<u>x = 1.566</u>
